Our take: StewAI suits people who use Claude, ChatGPT or other agents and want pre-tested workflow recipes, such as survey simulation or forecast analysis, that run on credits starting from a free 500 per month.
Main limitation: Usage is credit-limited on every plan, and simulated outputs are described as hypotheses rather than research data.

What is StewAI, and how does it work?
StewAI offers specialized, pre-tested workflows called recipes that take over demanding tasks and return results to an AI agent. The site lists hundreds of ready-to-run recipes, such as market research and forecast analysis, and says an agent can build one if none fits. It connects through a plugin for Claude, ChatGPT and other agents with email sign-in and no API key, and recipes can also be run directly from the Marketplace without an agent.
